Hi @Progressor welcome to the forum. There are currently some MIDI capture issues particularly regarding tempo which will be resolved in the upcoming Scaler 3.1.0.6 update, due April 30th. These are listed on the forum page below:
But to clarify some of your issues, it sounds like you are using MIDI capture to record activity in Scaler 3, but instead of dragging the captured MIDI to your DAW, you want to drag to Scaler?
This should be possible by dragging to a user track. So on the arrange page, click + to add a new track, then under articulations select user. Note that MIDI clips on user tracks are static and detached from the main track chords. So they will simply play the notes as they are and not adapt to chord changes.
There are some minor issues regarding DAW sync which will also be addressed soon. These are noted on the page linked above, however it should be working properly in Logic. Note that with DAW sync engaged, pressing play in Scaler 3 will only play Scaler 3’s main track and not Logic. For Logic to play along you will need to press Logic’s play button.
